The implementation of the invention

Some exemplary embodiments illustrated in the accompanying drawings are discussed in detail below. The following description refers to the accompanying drawings, in which, in different figures, the same reference numerals represent the same or similar elements, unless otherwise indicated. The implementations described in the following description of embodiments do not represent all implementations corresponding to the present invention. On the contrary, they are only examples of devices and methods corresponding to aspects related to the present invention according to the attached claims.

In the prior art, as a rule, the same color space display method is used for each frame of an image displayed by a terminal. The displayed image frame is usually obtained by overlaying multiple layers. However, not all layers of the frame are suitable for the same color space. For example, the smartphone’s lock screen interface contains a status bar layer, a wallpaper layer, and a desktop icon layer. The status bar layer and the desktop icon layer belong to the user interface (PI) layer, which is an artificially created, initially good-looking layer. But if the PI layer is mapped to an incorrect color space, then the aesthetics of the presentation of this PI layer is degraded. With this in mind, the present invention provides the following exemplary embodiments.

FIG. 1 is a flowchart illustrating a method of displaying on a color space in accordance with an exemplary embodiment. This embodiment is described by an example implementation of the proposed method in a terminal configured to process images. The specified method contains the following steps.

At step 102, at least one label of the type of color space of at least one layer added during the formation of the specified layer is obtained.

In step 104, based on the at least one color space type label, at least one color space corresponding to the at least one layer is determined.

In step 106, said at least one layer is mapped onto said at least one corresponding color space.

At step 108, an overlay of the at least one layer mapped onto the at least one corresponding color space is performed to form and display the image to be displayed.

As a result, by obtaining at least one label such as a color space of at least one layer; determining at least one color space corresponding to said at least one layer based on said at least one color space type label; mapping said at least one layer onto at least one corresponding color space; and overlaying said at least one layer mapped onto said at least one corresponding color space in order to form and output an image to be displayed, the color space display method proposed by this embodiment eliminates the disadvantage that some layers the images to be displayed in the terminal look bad when using the same color space to show all the frames of the image, and gives you the opportunity The technical result consists in the fact that the different layers of each image to be demonstrate at a terminal are displayed on a different color space according to the individual type of color space of each layer, whereby each layer is as follows, as required. For example, more accurate colors can be used for the natural layer, and brighter colors can be used for the user interface layer, which creates a more favorable overall impression of the image displayed by the terminal.

FIG. 2 is a diagram illustrating a layer structure of a display frame of an image 10 in accordance with an exemplary embodiment. Image 10 shown is the start page of a smartphone. This smartphone’s start page contains the following three layers: status bar layer 12, desktop icon layer 14 and wallpaper layer 16. The status bar layer 12 is the uppermost layer, the desktop icon layer 14 is an intermediate layer, and the wallpaper layer 16 is the lowermost layer. If the overlying layer is opaque, then it makes the underlying layer invisible. The order of overlapping layers is determined by the order values in the z direction corresponding to the specified layers. The order in the z direction defines a hierarchical relationship between layers (which are also called display objects). Typically, a layer that corresponds to a higher order value in the z direction is overlying for a layer that corresponds to a lower order value in the z direction.

In the terminal, the displayed image 10 is formed by synthesis of the three above layers. The sources of these layers can be the same or different.

As one of the possibilities, from a software point of view, the sources of layers include a desktop application, a state application, a wallpaper application, a third-party application, etc. Layers from the specified application programs are combined into the resulting displayed image by the image synthesis program of the operating system. For example, on Android, the SurfaceFlinger layer is responsible for merging layers.

As one of the possibilities, from a hardware point of view, the number of layer sources includes at least one device from a central processing unit (CPU), a graphics processing unit (GPU), and a video decoder chip. These layers are combined in the application processor (PPP), and then displayed on the display screen for demonstration purposes.

As one option, each layer is classified as a natural layer or as a user interface (UI) layer. By a natural layer is meant a layer formed on the basis of naturally existing objects, or a layer formed by emulating naturally existing objects. Typical natural layers include: a layer obtained by photographing with a camera, a layer of a frame obtained by decoding video material, a layer from the virtual world, built in real time by the software core of a computer game, etc. The PI layer is understood as a layer intended for the implementation of human – machine interaction. Typically, a PI layer is artificially created. Different color spaces are better for layers of different types. For example, the NTSC color space is better suited for the natural layer, and the sRGB color space is better suited for the PI layer.

FIG. 3 is a flowchart illustrating a method of displaying on a color space in accordance with an exemplary embodiment. This embodiment is described by an example implementation of the proposed method in the terminal. The method contains the following steps.

At step 301, the fulfillment of the triggering condition of the automatic display function on the color space is checked.

As one of the possibilities, the conditions for starting the function of automatic display on the color space include at least one of the following conditions, without limiting the possible conditions to the listed conditions.

Condition 1: when a conditional application program is launched, for example, a media player program.

Condition 2: When the auto color space display function is configured to be turned on by the user.

If the specified start condition is fulfilled, then proceed to step 302. If the specified start condition is not fulfilled, no processing is performed and the color spaces of the screen itself or the color spaces currently used by the operating system are used.

At step 302, if the specified launch condition is met, then the layer generated by the application program is obtained and the label of the color space type corresponding to the specified layer and added when the specified application is formed to form the specified layer is obtained.

In the normal operation of the terminal, each application program forms its own layer. For example, the desktop application generates an icon layer, the wallpaper application generates a wallpaper layer, and the status bar application generates a status bar layer.

As one of the possibilities, each application program also generates a label of the type of color space corresponding to the specified layer, based on the content of the specified layer.

For example, the icon layer contains the icons of many application programs. Since all of these icons are artificially created PI icons, the specified desktop application generates a label corresponding to the specified icon layer, such as the color space Label1. Also, as an example, since the wallpaper layer is a photograph of a natural landscape, the wallpaper application generates a label such as the color space “Label 2” corresponding to the specified wallpaper layer. As another example, since the status bar layer is an artificially created PI layer, the status bar application generates a label of the type of color space “Label 1” corresponding to the specified status bar layer.

An image synthesizer or image synthesis program in the terminal receives a layer formed by each application program and a color space type label corresponding to this layer.

In step 303, at least one color space corresponding to the at least one layer is determined based on the at least one color space type label.

As an illustration, if the label for the type of color space of the icon layer is “Label 1”, then the color space sRGB is set as the color space corresponding to the specified icon layer. If the label of the color space type of the wallpaper layer is “Label 2”, then the NTSC color space is set as the color space corresponding to the specified wallpaper layer.

In step 304, said at least one layer is mapped onto said at least one corresponding color space.

By way of illustration, the terminal accordingly maps said at least one layer to at least one corresponding color space.

For example, when the color space corresponding to the layer is the sRGB color space, the terminal maps this layer to the sRGB color space. As another example, when a color space corresponding to a layer is an NTSC color space, the terminal maps that layer to an NTSC color space.

At step 305, an overlap order of the specified at least one layer is obtained.

The terminal also obtains the order value in the z direction of each layer and determines the layer stacking order based on the specified order value in the z direction of each layer. Typically, a layer that corresponds to a higher order value in the z direction is overlying for a layer that corresponds to a lower order value in the z direction.

At step 306, in accordance with the specified overlay order, the specified at least one layer is overlaid to obtain an image to be displayed.

The terminal, in accordance with the specified overlay order, performs the overlay of layers in order to obtain a frame of the image to be demonstrated. Each frame of the image to be demonstrated is obtained by superimposing at least one layer of the specified image frame.

At step 307, the image to be displayed is displayed on the display screen for demonstration purposes.

The terminal, for the purpose of demonstration, displays the image to be demonstrated on the screen of its display.

As a result, by obtaining at least one label such as a color space of at least one layer; determining at least one color space corresponding to said at least one layer based on said at least one color space type label; mapping said at least one layer onto at least one corresponding color space; and overlaying said at least one layer mapped onto said at least one corresponding color space in order to form and output an image to be displayed, the color space display method proposed by this embodiment eliminates the disadvantage that some layers the images to be displayed in the terminal look bad when using the same color space to show all the frames of the image, and gives you the opportunity The technical result consists in the fact that the different layers of each image to be demonstrate at a terminal are displayed on a different color space according to the individual type of color space of each layer, whereby each layer is as follows, as required. For example, more accurate colors can be used for the natural layer, and brighter colors can be used for the user interface layer, which creates a more favorable overall impression of the image displayed by the terminal.

Since it is assumed that the opaque pixels of the overlying layer cover the pixels of the underlying layers, some areas in the underlying layers will ultimately not be presented to users. In other words, the entire demonstration area of the layer may be the current demonstration area, or the layer may contain the current demonstration area and the irrelevant demonstration area. The current demonstration area is visible in the final displayed image, and the irrelevant demonstration area in the displayed image is not visible. The present invention also provides the following embodiments of the invention, aimed at reducing the amount of computation.

FIG. 4 is a flowchart illustrating a method for displaying on a color space in accordance with an exemplary embodiment. This embodiment is described by an example implementation of the proposed method in the terminal. The specified method contains the following steps.

At step 401, the fulfillment of the triggering condition of the automatic mapping function to the color space is checked.

As one of the possibilities, the conditions for starting the function of automatic display on the color space include at least one of the following conditions, without limiting the possible conditions to the listed conditions.

Condition 1: when a conditional application program is launched, for example, a media player program.

Condition 2: When the auto color space display function is configured to be turned on by the user.

If the specified start condition is fulfilled, then proceed to step 402. If the specified start condition is not fulfilled, no processing is performed and the color spaces of the screen itself or the color spaces currently used by the operating system are used.

At step 402, if the specified launch condition is met, then the layer generated by the application program is obtained and the label of the color space type corresponding to the specified layer and added when the specified layer is formed by the specified application program is obtained.

In the normal operation of the terminal, each application program forms its own layer. For example, the desktop application generates an icon layer, the wallpaper application generates a wallpaper layer, and the status bar application generates a status bar layer.

As one of the possibilities, each application program also generates a label of the type of color space corresponding to the specified layer, based on the content of the specified layer.

For example, the icon layer contains the icons of many application programs. Since all of these icons are artificially created PI icons, the specified desktop application generates a label corresponding to the specified icon layer, such as the color space Label1. Also, as an example, since the wallpaper layer is a photograph of a natural landscape, the wallpaper application generates a label such as the color space “Label 2” corresponding to the specified wallpaper layer. As another example, since the status bar layer is an artificially created PI layer, the status bar application generates a label of the type of color space “Label 1” corresponding to the specified status bar layer.

An image synthesizer or image synthesis program in the terminal receives a layer formed by each application program and a color space type label corresponding to this layer.

At 403, at least one color space corresponding to the at least one layer is determined based on the at least one color space type label.

As an illustration, if the label for the type of color space of the icon layer is “Label 1”, then the color space sRGB is set as the color space corresponding to the specified icon layer. If the label of the color space type of the wallpaper layer is “Label 2”, then the NTSC color space is set as the color space corresponding to the specified wallpaper layer.

At step 404, the blending order of the specified at least one layer is obtained.

The terminal also obtains the order value in the z direction of each layer and determines the layer stacking order based on the specified order value in the z direction of each layer. Typically, a layer that corresponds to a higher order value in the z direction is overlying for a layer that corresponds to a lower order value in the z direction.

At step 405, in accordance with the specified overlay order, at least one corresponding actual display area of the at least one layer is marked.

As one of the possibilities, the actual demonstration area of each layer is understood as the region of the current layer that is not covered by the overlying layers. In other words, the actual area of the demonstration of each layer refers to the area that is visible in the image.

Layers are superimposed according to their order values in the z direction. When the overlying pixels in the overlying layer are opaque, the underlying pixels in the underlying layer located directly below the specified overlying pixels will be closed and will not appear in the displayed image.

The terminal marks the current area of demonstration of each of the layers in accordance with the specified sequence of layers. As one of the possibilities, when the layer is the uppermost layer, the entire area of this layer is marked as the current area of the demonstration. When the layer is not the uppermost layer, at least one layer that is overlying with respect to the layer is obtained. The positions of the pixels in the layer corresponding to the opaque pixels in at least one upper layer are marked, as a result of which the first set of pixels is formed, and then the second set of pixels containing the pixels of the layer that are not included in the first set of pixels is formed and set as the current demonstration area .

At step 406, at least one effective display area of the specified at least one layer is mapped to the specified at least one corresponding color space.

As an illustration, the terminal displays the current demonstration area of a layer in the color space corresponding to that layer. For example, when the color space corresponding to the layer is the sRGB color space, the terminal maps this current display area of the specified layer to the sRGB color space. As another example, when the color space corresponding to the specified layer is an NTSC color space, the terminal maps this current display area of the specified layer to the NTSC color space.

It should be noted that steps 404 and 405 are optional steps. At step 406, for each layer, if the current demonstration area of the layer is not specified, then the entire demonstration area of this layer is displayed directly on the color space corresponding to this layer.

At step 407, in accordance with the specified overlay order, the specified at least one layer is overlaid to obtain an image to be displayed.

The terminal, in accordance with the specified overlay order, performs the overlay of layers in order to obtain a frame of the image to be demonstrated. Each frame of the image to be demonstrated is obtained by superimposing at least one layer of the specified image frame.

At step 408, the image to be displayed is displayed on the display screen for demonstration purposes.

For demonstration purposes, the terminal displays the image to be displayed on the display screen.

It should be noted that the specific examples of the color space type label and the color space indicated in the embodiments of the present invention are provided only to simplify the understanding of these embodiments and do not impose restrictions on the color space type label and color space.

As a result, by obtaining at least one color space type label of at least one layer, determining at least one color space corresponding to the at least one layer based on the at least one color space type label, displaying at least one layer on at least one corresponding color space, and overlaying the specified at least one layer displayed on the specified at least one corresponding e color space, in order to form and output the image to be displayed, the color space display method proposed by this embodiment eliminates the disadvantage that some layers of the image to be displayed in the terminal do not look good when using one color space for demonstration all frames of the image, and makes it possible to obtain a technical result, consisting in the fact that the different layers of each image to be demonstrated on the term e, displayed on a different color space according to the individual type of color space of each layer, whereby each layer is as follows, as required. For example, more accurate colors can be used for the natural layer, and brighter colors can be used for the user interface layer, which creates a more favorable overall impression of the image displayed by the terminal.

In addition, by performing the display only for the actual demonstration area of each layer, the color space display method proposed by this embodiment makes it possible to reduce the amount of terminal calculations and speed up the calculations performed by the terminal when displayed on the color space. As one of the possibilities, it is also advisable for the terminal to display on the color space only for the current area of demonstration of each layer.
